COTTER, P.A.*; EVERSON, J.J.; RODNICK, K.J.: What comes in must go out:Ventricular blood flow patterns in the Rainbow Trout Hemodynamic parameters in fish are often measured using invasive techniques, limiting the use of repeated measure experimental designs. We used high-resolution (10 MHz) echocardiography, and doppler analysis of sagittal images to determine ventricular filling (diastolic) and […]

HOAGLAND, T.M.*; HANCOCK, T.V.; HILLMAN, S.S.: Systemic Vascular Compliance in Two Amphibians The mean circulatory filling pressure (MCFP), vascular compliance (VC) and unstressed blood volume (USBV) were measured in Bufo marinus and Rana catesbeiana, using in vivo methods. These values are integral for the understanding of venous function and cardiovascular homeostasis, and have been determined […]

Wilkens, J.L.; Yazawa, T.; Shinozaki, T.; ter Keurs, HEDJ: Sites and mode of action of proctolin and F2 on lobster cardiac muscle At low concentration (10-10 M), the peptide hormones proctolin (PR) and F2 cause an increase in the amplitude of electrically evoked contractions of lobster heart ostial valve muscle. At higher concentrations (PR >10-9 […]

Hunt von Herbing, I.*; Cashon, B.: Sickling in fish red blood cells The occurrence of the mutant hemoglobin Hb S in human red blood cells results in sickle cell anemia. In other animals,oxygen-linked sickling of red blood cells is largely unknown.In Atlantic cod red blood cells under oxygenated conditions cell morphology appears normal,but under low-oxygen […]
